About this trial
The study is intended to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of AZD4512 in patients with relapsed/refractory B-Cell acute lymphoblastic leukemia (r/r B-ALL).
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
16 years old in Module 1 (US only: ≥18year)
12 years old in Module 2
Participants must have relapsed or refractory B-ALL ('relapsed' defined as bone marrow blasts > 5% or reappearance of blasts in PB)
Module 1 (DE): Ph(-) B-ALL and Ph(+) B-ALL - R/R
Disqualifiers
Burkitt lymphoma and leukemia
Isolated extramedullary disease; Active testicular or CNS (> CNS1) involvement
Unresolved non-heme toxicities Grade ≥ 2 (except alopecia, stable Grade ≤ 2 neuropathy, vitiligo, endocrine disorders controlled with therapy)
History of drug-induced non-infectious ILD/pneumonitis requiring oral or IV steroids or supplemental oxygen or where suspected ILD/pneumonitis cannot be ruled out by imaging at screening
Trial design
Sequential
Treatments tested in this trial
AZD4512 monotherapy
Combination productPatients will receive AZD4512 as monotherapy via intravenous infusion. AZD4512 is an antibody-drug conjugate targeting CD22
Treatment groups
Trial outcomes
Primary outcomes
Module 1 (Dose Escalation): Number of participants with dose-limiting toxicities (DLTs).
DLTs are dose-limiting toxicities as defined in the study protocol.
Module 1 (Dose Escalation): Frequency, duration and severity of treatment-emergent adverse events (TEAEs), treatment-related adverse events (TRAEs), and serious adverse events (SAEs)
Assessed by the CTCAE criteria version 5.0
Module 1 (Dose Escalation): Frequency of dose interruptions, modifications, delays, and discontinuations due to AEs
Module 1 (Dose Escalation): Number of participants with clinically significant changes in laboratory values, ECGs, performance status, and vital signs
Secondary outcomes
Module 1 (Dose Escalation): Plasma PK parameters of AZD4512
To characterize the PK of AZD4512 as monotherapy in participants with R/R B-ALL.
Module 1 (Dose Escalation): Total antibody and total unconjugated payload
To characterize the PK of AZD4512 as monotherapy in participants with R/R B-ALL.
Module 1 (Dose Escalation): Area Under Curve (AUC)
To characterize the PK of AZD4512 as monotherapy in participants with R/R B-ALL.
Module 1 (Dose Escalation): Peak Plasma Concentration (Cmax)
To characterize the PK of AZD4512 as monotherapy in participants with R/R B-ALL.
